[DCCP]: Initial implementation

Development to this point was done on a subversion repository at:

http://oops.ghostprotocols.net:81/cgi-bin/viewcvs.cgi/dccp-2.6/

This repository will be kept at this site for the foreseable future,
so that interested parties can see the history of this code,
attributions, etc.

If I ever decide to take this offline I'll provide the full history at
some other suitable place.

+          CCID 3 denotes TCP-Friendly Rate Control (TFRC), an equation-based
+          rate-controlled congestion control mechanism.  TFRC is designed to
+          be reasonably fair when competing for bandwidth with TCP-like flows,
+          where a flow is "reasonably fair" if its sending rate is generally
+          within a factor of two of the sending rate of a TCP flow under the
+          same conditions.  However, TFRC has a much lower variation of
+          throughput over time compared with TCP, which makes CCID 3 more
+          suitable than CCID 2 for applications such streaming media where a
+          relatively smooth sending rate is of importance.
+
+          CCID 3 is further described in [CCID 3 PROFILE]. The TFRC
+          congestion control algorithms were initially described in RFC 3448.
